A work piece is positioned with respect to a folding blade on a positioning table and electromechanical means, acting through a toggle linkage, raise a folding blade through a slot in the table to fold the work piece and simultaneously jam it into a pair of closed jaws mounted on a transfer device which crease the work piece and carry it to a second position where the creased work piece is released to fall upon a conveyor belt. |
